Add all files to a commit except a single file?
...
@MariusKavansky You can use all of these forms. If you use main/* it is necessary to add -- in front of it to let git know that it is a path. The other two variants work without including the two dashes. (Tested in command prompt on Windows 7 with msysGit)

What is the preferred/idiomatic way to insert into a map?
...e. As other answers have noted, this has several advantages over the other forms:
The operator[] approach requires the mapped type to be assignable, which isn't always the case.
The operator[] approach can overwrite existing elements, and gives you no way to tell whether this has happened.
The oth...
Explain the encapsulated anonymous function syntax
...e grammar of a FunctionDeclaration looks like this:
function Identifier ( FormalParameterListopt ) { FunctionBody }
And FunctionExpressions:
function Identifieropt ( FormalParameterListopt ) { FunctionBody }

Git diff to show only lines that have been modified
...lly be used as patches to source files, which is impossible without that information. The only way to remove it would be to post-process it yourself, such as via git diff | egrep "^(\+|-) ".

Why do we not have a virtual constructor in C++?
...tors?
A virtual call is a mechanism to get work done given partial

need to know the e...

string About = string.Format(CultureInfo.InvariantCulture, @"YourApp Version {0}.{1}.{2} (r{3})", v.Major, v.Minor, v.Build, v.Revision);

How do you disable the unused variable warnings coming out of gcc in 3rd party code I do not wish to
...e safe. In your code, you can suppress the warnings for variables and even formal parameters by using GCC's unused attribute. Lets say you have this code snippet:

unsigned tmp;
std::cout << number << std::endl;
}

How can I pass selected row to commandLink inside dataTable or ui:repeat?

}
This only requires that the datamodel is preserved for the form submit request. Best is to put the bean in the view scope by @ViewScoped.
You can even pass the entire item object:
<h:commandLink action="#{bean.insert(item)}" value="insert" />
with:
public void insert(Item it...
Is there a difference between using a dict literal and a dict constructor?
...he dict() constructor gives you more flexibility because of the variety of forms of input it takes. For example, you can provide it with an iterator of pairs, and it will treat them as key/value pairs.
I have no idea why PyCharm would offer to convert one form to the other.
